METALLIC BARREL.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed April 2, 1906. Serial No. 309,561.

To all whom it may concern: I

Be it known that I, CHARLES L. CoFFIN, a citizen of the United States of America,residing at N acoochie, in the county of White and State of Georgia, have invented certain new and useful Improvements in Metallic Barrels, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates particularly to metallic packages or barrels of the insulated type wherein the body is composed of shellsections spaced one from another to provide an insulating space or chamber; and it consists in the novel and peculiar construction of a barrel of this type and in various details of construction, as will be more fully hereinafter set forth and illustrated.

unt

In the drawings, Figure 1 is a vertical central section through a metallic barrel embodying my invention. Fig. 2 is a similar view showing a modified construction. Fi s. 3, 4, and 5 are modifications. Fig. 6 isa (Ietached view of one of the drawn sections of which either of the shells may be composed, and Figs. 7, 8, and 9 are detached sectional views illustrating the means of uniting the drawn sections.

Referring to Fig. 1, A represents an outer shell, B an inner shell spaced from the outer to form an annular insulating-chamber C and insulating-spaces D and E at the ends. In this instance the inner shell is composed of. a cylindrical section F, provided with depressed heads G and H, the heads being flanged, as atI, and the flanges united to the cylindrical body in any preferred manner, preferably by welding. The outer section referred to is composed of two stamped or drawn sections J and K, formed each with a head, as L, which in turn has formed in it an annular spacing-flange M, adapted to engage the ends of the inner section.

In assembling the parts the drawn sections are placed over the ends of the inner section 1 an engagement is effected between the inner-section ends and the annular flange. The drawn sections are united at their meeting edges by means of a seam 0, formed from the adjoining. portions of the sections. One of the sections is provided, preferably, with an angle-shaped flange P, Fig. 7, while the complementary sectionhas formed therein a lateral annular flange Q. In forming the seam the upwardly-projecting portion R of the flange l is folded over into contact with the flange Q, and then both flanges are bent or pressed over into contact with the body of the outer section, as indicated in Fig. 9,a tight and waterproof seam being thus produced.

In Fig. 2 I have shown the outer section formed of a single cylindrical section constituting the body and heads set within the body, as previously described, and formed each with an annular retaining and spacing flange, as R. The inner section in this instance is composed of complementary drawn sections engaging the outer section and united to one another, as just described.

In big. 3 both the inner and outer shells are shown as composed of complementary drawn sections, each section being so curved or flared as to produce when assembled the bilge form of barrel.

in h ig. 4 the construction is similar to that of Fig, 3 in so far as the inner shell is 'concerned. The outer shell is formed of complementary drawn sections S and T, united by a third or intermediate section U, the connection between the sections being by means inner shell of the drawn cylindrical section as indicated at V and W and the outer shell in bilge form, having preferably the intermediate uniting section Y.

, From the forgoing description it will be observed that either or both of the shells may be composed of drawn sections and that said sections may be either united directly at their meeting edges or portions or by means of a third intermediate section, ,as described, the v latter being sometimes the preferable construction, as it requires stamp-sections of less depth, which is desirable for obvious reasons.

What I claim is 1. A metallic barrel consisting of two closed shells arranged one-within the other, one being formed of oppositelydisposed drawn headed sections, and annular spacingflanges upon the heads or ends of the complementary shell with which the drawn sections engage.

2. A metallic barrel comprising an outer inclosingcasing composed of two drawn headed sections formed each with a spacingfiange, and an inner closed shell engaging the flanges.

3. A metallic barrel consisting of an outer shell or casing composed of two drawn headed sections, the heads being oppositely disposed l within the other, one being formed of oppositely-disposed drawn headed sections, and spacingflanges upon the heads of one of the casings engaging the ends or heads of the complementary casing.

In testimony whereof I aflix my signature in and formed each with an annular spaclngpresence of two witnesses.

flange, and an inner closed shell engaging an held agamst relative movement by the headflanges.

4. A metallic barrel comprising complementary inclosing casings arranged one CHARLES L. COFFIN.
